This change came so suddenly, so quickly, that people could not give birth to any courage to resist.

It's just strange that the mound stopped abruptly after crushing the cold clouds, and did not go further in the direction of the waterfall.

The hum of the hydroelectric generators continued, still operating normally, unaffected.

After a puff of dirt fell, half of his head popped out of the cold clouds.

He half-squinted, looking at the strange things that were happening in front of him with a bewildered expression.

I saw a bucket-thick tree root wrapped around me, like the giant python that almost killed me a month ago.

It's just that at this time, although he was bound by the roots, he was not as breathless as the last time he was tied up by a giant python.

He could even clearly feel that the roots of the tree were caressing his smooth skin with countless soft fibrous roots, as if to soothe a crying child.

What's even more strange is that these fibrous roots tremble constantly after coming into contact with the electric current surrounding their bodies, like a bride on a wedding night, and want to refuse to welcome back......

It's so speechless!

Who would have thought that the roots of the tree would be alive and could express such complex emotions?

At this moment, Han Tianyun clearly felt that the electricity on his body was constantly surging towards the roots of the tree, and even a special suction force seemed to be generated in the thick roots, sucking all the electrical energy away.

This...... Sure enough, it's a demon tree!

Han Tianyun remembered the previous small flower breakthrough, and the giant tree suddenly stretched out its branches to block the purple light, although he was surprised by the sudden arrival of the tree roots at this time, but it was not too surprising.

I just feel a little depressed.

After all, it doesn't feel good that your life is completely in the hands of someone else.

At this time, he felt that his body had become a conductor.

Obviously, there was electricity flowing through his body, but there was no trace of it entering the countless fibrous roots, becoming the nutrients of the big tree, and even he didn't doubt it at all, as long as this demon tree wanted to, it could instantly suck itself into a human dry.

Thinking of this, Han Tianyun felt a little cold in his heart.

"Let it go...... Open him!" The stammering little flower had rushed back from under the cliff, and roared fiercely at the roots of the trees that were outcropping from the ground.

The roots of the tree were silent, but when she came near, a branch of the thickness of a bowl suddenly stretched out and tied her firmly.

Then, it didn't move again, just greedily absorbed the electric energy from the copper wire in Han Tianyun's hand.

Soon, Han Tianyun figured it out.

The purpose of this demon tree is the same as Xiaohua's, it is the electricity in his hand.

As for the two children, they are not in its eyes at all.

Feeling the greed, excitement, joy and other emotions that filled the roots, Han Tianyun's mind gradually calmed down.

It turns out that the aura of this world is electricity!

As long as there is electricity, the possibilities are endless.

In his mind, he has a clearer understanding of the setting of this world.

"The generator will only work for a maximum of one hour, and if it continues, it will burn out. ”

Half an hour passed in a flash, and Han Tianyun twisted his neck to look at the generator that was still running, and couldn't help but say coldly to the roots of the tree in front of him.

He didn't know if the root would understand what he meant, but he had to make some effort.

After all, it took him a month to experiment with the generator.

Whoa!

Unexpectedly, the thick roots of the tree quickly let go of the cold sky clouds and small flowers, and shrank back towards the muddy grass, but they understood his words in seconds.

“......”

The two looked at each other, staring at the roots of the tree that quickly disappeared to the ground, and were speechless for a while.

......

In the days that followed, Han Tianyun's daily life was to occasionally go into the forest with Xiaohua to hunt and maintain the life of the three of them, but most of the time, they were soaked in the stone ground next to the waterfall, constantly improving and repairing the generator, constantly generating electricity, and constantly quenching the body.

Of course, for him, the fire and poison outbreak that always occurs at noon every day is never absent.

Time passed in this constant repetition, and another month passed in the blink of an eye.

This month, Xiaohua will come to charge the electricity for half an hour every day, and I don't know where the electricity is stored after entering her body.

And her cultivation is improving rapidly at a speed that is visible to the naked eye.

Even last time, Han Tianyun saw an arc of lightning shoot out of her palm, killing a spotted leopard that flew towards her.

Han Tianyun was envious and helpless, so he could only continue to extend the time for the current quenching.

But a month has passed, and he still hasn't broken through.

Although it felt like his weak body seemed to be stronger and stronger during this time, it was nothing more than that.

After Xiaohua was able to speak normally, he had specifically consulted about this issue.

But Xiaohua's understanding of cultivation is even worse than his.

At least he has many passages from fantasy novels as references, and the little girl is just a real primitive, full of indigenous.

From Xiaohua's words, he already knew that this little girl had lived in the hollow halfway up the demon tree since she could remember, and when she was hungry, she came to the stone ground to hunt wild beasts when the beast tide came, and when she was thirsty, she climbed among the leaves to drink the dew on the leaves, and in every thunderstorm, she climbed into the high canopy, and hid among the branches and leaves to receive the thunder and lightning quenching.

Before the heavens changed, she hadn't even been to the west side of the tree.

This is also the reason why Han Tianyun and the nurse have lived under the tree hole in the west for five or six years, but they have never seen her.

This demon tree is really a bit too big.

After learning that Xiaohua lived alone in the tree hole in the southwest, Han Tianyun carefully searched around the demon tree, but unfortunately, no trace of human existence was found on the east or north side of the big tree.

In general, there should be only three of them under the big tree.

With Xiaohua's life as a blank sheet of paper, what kind of cultivation knowledge can you get from her?

Even she doesn't know what the changes in her body are all about!

Helpless, Han Tianyun could only put his hope on the demon tree that was dead and begging for nothing.

Every day for a month, the demon tree would stick out its thick roots and come close to him, nakedly snatching the electricity from the generator.

It can even be said that most of the electrical energy emitted by the generator is absorbed by the demon tree.

Xiaohua can fill up in half an hour a day at most, and he himself is burned by the electricity at most, and his skin seems to have absorbed nothing.

The demon tree is different, if it is generating electricity twenty-four hours a day, Han Tianyun believes that the demon tree can also absorb all the electricity emitted, and it will not be too much at all.

Every time Han Tianyun just started to quench his body, he came with joy and hunger, and every time he wrapped Han Tianyun with tree roots, using his body as a conductor, sucking out all the electric energy around his body, leaving nothing left.

"You...... Don't deceive people too much!" looked at the roots of the tree that came as scheduled, and today's cold sky cloud roared sadly and angrily.

Why he has not succeeded in quenching his body and entered the next realm, he thinks that to a large extent, it is caused by the roots of the tree sucking all the electrical energy out of his body.

This annoyed him.

At this moment, a slightly vicissitudes of thought came out of the messy fibrous roots and entered Han Tianyun's mind, making him instantly understand the meaning of the tree roots.

That seems to mean that the current is a waste on him anyway.

"What the hell, can you still communicate with people?"

Han Tianyun was stunned again, and when he came back to his senses, he couldn't help but scold.

But this time the roots of the tree did not change, and they just tied him up in it and began to greedily absorb electricity.

"What do you mean by wasting electricity on me?"

Han Tianyun thought about it and continued to talk to himself to the roots on his body.

The roots of the tree trembled slightly in response, but there was no more expression.

These days, Han Tianyun has seriously understood the changes in his body and discovered a strange phenomenon.

Every time the current quenched his body, the current on his skin passed through rapidly, and it would not enter the blood and internal organs in his body at all.

Not to mention that once it touches the roots of the tree, it pours out like a lake bursting its banks, completely sucked up by the roots, and nothing remains.

Figuratively speaking, these currents are like water flows, but they only stay in his epidermis and do not mix with the bloodstream.

Because of this discovery, he has made a lot of efforts in the past few days.

For example, the day before yesterday, he deliberately broke his fingertips and connected the copper wire to the bleeding place, but the current still did not enter the bloodstream.

Today, for example, he has put copper wire under his tongue, but the result is still the same.

Therefore, he was very concerned about the idea passed on by the demon tree, and wanted to find some reason for it.

It's a pity that no matter how he induces, he talks to himself like a madman, trying to get the demon tree to give him some guidance, but the roots of the tree have not changed in any way, but they are extremely greedy to absorb a steady stream of electricity.

In the evening, the roots of the demon tree quickly receded again, and Han Tianyun reluctantly moved the boulder away and lifted the water turbine out of the waterfall.

There is no way, to build a generator in this primitive land, if you want to cut off the power, you can only use this primitive method.

After this period of repair and improvement, Han Tianyun has increased the running time of the generator to about five hours.

Today is destined to be another day of failure, Han Tianyun was a little depressed in his heart, and walked up the path dejectedly, preparing to return to the tree hole to rest.

At this time, the afterglow of the setting sun shines obliquely through the rocks between the cliffs into the smooth stone ground under the demon tree.

Xiaohua, who had returned from hunting in the forest alone, was carrying a wild boar and came slowly from the meadow to the north.

The huge demon tree, which was full of electric energy, suddenly danced without wind, and a terrifying change occurred.
